I'd drive it for awhile and see if the springs settle first.
Could try removing the bottom leaf but I'm not sure you can do that with the iso clamp setup.
Earlier cars you could flip the front hanger upside down and get an inch of drop, just watch the pinion angle.

I added 1" spacers between spring and isolator.
Had to remove the stud bushing and installed it over the block pin to fit into the isolator.
then added alluminium spacers too to the U bolts, between both plates, just to keep safe the isolators from being hardly smashed when tightening.
will find the pic and post.
EDITING... not easy to see, but... there is the block in between the isolator and spring and the shiny pieces are the aluminium spacers which I made and installed like somehow as a colapsible bushing to keep the isolators safe
and is true, there is a bushing on guide stud. This guide stud is also thicker than earliers ( 3/8" instead 5/16" from earliers )
I removed the top bushing and installed on top of the spacer guide.
here the non iso assembly vs the iso assembly

I was on a similar issue with new springs being higher than should be hence the reason I installed the blocks, but after 10 years riding my car ( plus 4 and a half sitting at body shop ) I think now can get back the assembly without the block spacer

If I wanted to eliminate the isolator and add lowering blocks, what would I need to do that?

get 71/72 B body lower shock plates ( maybe earliers works too ? ) and remove the top and bottom guide stud bushings. maybe even replace the stud itself ( stud threads can not be enough )
I guess even the guide studs on 73/74 are 3/8" from the 5/16" used on earliers, should still fit fine. The bottom shock plate should still get room to acomodate the "bigger" studs.
mostly sure will need also shorter U bolts, like earliers
